Definitions
- the present invention relates to the drying of petroleum fractions weakly charged with water, intended to be treated in units whose functioning is sensitive to the presence of water in their loads.
- the charge of paraffinic hydrocarbons is brought into contact with a solid chemical drying agent, which has an active surface of between 1 and 500 m 2 / g.
- the dried charge is then isomerized at a temperature of 50 at 350 ° C, in the presence of hydrogen, by passage over a catalyst.
- the agent chemical drying is a chemically inert support to water, surface of which chemical compounds which are combined have been deposited easily with water.
- the chemical compounds can be either alkali metals, such as potassium or sodium, either chlorides easily hydrolyzable metals, such as aluminum chloride.
- Another process for drying a hydrocarbon feedstock consists of passing this charge through dryers through a bed of adsorbent, which retains water by molecular interaction.
- the adsorbent product is generally alumina or sieve molecular. It gradually saturates with water and must be regenerated periodically.
- This transfer area depends on the conditions the periodicity of the regeneration of the adsorbent and its aging.
- the transfer zone At the start of the adsorption cycle, the transfer zone is close of the dryer inlet and the water content of the outlet charge is very weak. At the end of the adsorption phase, the transfer zone is near the dryer outlet and the load may not meets more than water saturated adsorbent.
- the limit of detection of measuring devices of the content feed water being of the order of 0.1 ppm by weight, when such content is detected, there have already been detrimental effects to the good operation of the hydrocarbon charge treatment unit, such as a very significant deactivation of the catalyst in the case an isomerization unit.
- the object of the present invention is precisely to remedy these disadvantages and to provide an economical, efficient and safe process, for drying a hydrocarbon feed.
- hydrocarbon radicals R1, R2, R3 and R4 are chosen from preferably in alkyl or aryl groups.
- the quantity of chemical compound injected is advantageously less than 1% by weight of this charge.
- the amount of chemical compound injected is less than 100 ppm by weight and, even more preferably, less than 1 ppm by weight of said charge.
- the method of the invention is implemented by diluting beforehand the quantity of chemical compound injected into at least one hydrocarbon.
- the dilution hydrocarbon can in particular be chosen from among the paraffinic hydrocarbons which contain 5 or 6 carbon atoms.
- the dilution hydrocarbon can be chosen among naphthenic hydrocarbons which contain 5 or 6 atoms of carbon.
- the chemical compound can be injected into said pipeline.
- the channeling of connection can advantageously be provided with a device mixer placed downstream of the injection point of the chemical compound.
- the process of the invention therefore provides an effective and economical drying of hydrocarbon charges at the inlet of treatment units sensitive to the presence of water.
- hydrocarbon radicals which allow better solubilization in the load and therefore facilitate and improve the desired dehydration.
- the unit shown schematically in Figure 1 is a isomerization unit of an oil cut containing paraffinic hydrocarbons with 5 or 6 carbon atoms and having a water content less than 50 ppm by weight.
- the petroleum cut to be isomerized arrives via line 1 in a dryer 2, which contains molecular sieve 3.
- the residual water content is measured using a hygrometer 5.
- a mixture 8 of dichloride is injected via line 6 into line 4 ethyl aluminum (AlCl 2 C 2 H 5 ) and hydrocarbons containing 5 or 6 carbon atoms, contained in a tank 9.
- the mixture of aluminum ethyl dichloride and hydrocarbons is added to the load circulating in line 4 to supply a static mixer 10, the output of which is connected by a line 12 to the entrance to a first isomerization reactor 13, which contains a catalyst composed of highly chlorinated alumina (chlorine content greater than 3% by weight) and platinum.
- Dry hydrogen is injected through line 11 into line 12, between the outlet of dryer 3 and the inlet of reactor 13.
- This first reactor 13 is connected by line 14 to the entrance to a second isomerization reactor 15, charged with a catalyst identical to the catalyst of the first reactor 13. The charge treated is discharged from reactor 15 via line 16.
- the isomerization unit also includes a regenerated dryer 17 pending and, not shown in FIG. 1, means for switching of the two dryers 3 and 17, as well as the means control of the flow rate of the ethyl dichloride mixture aluminum and hydrocarbons in line 6 at the feed rate in line 4, to ensure the proportionality of these two flows.
- Aluminum ethyl dichloride diluted in hydrocarbons injected by line 6 in line 4 reacts by hydrolysis with water residual contained in the charge from dryer 3, in particular in mixer 10, and, as it passes through line 12, it also reacts with traces of water possibly brought by the hydrogen injected.
- an amount of aluminum ethyl dichloride greater for example, is 20% greater than the amount strictly necessary for the elimination of these traces, which corresponds to the stoichiometric quantity to carry out the total hydrolysis of ethyl aluminum dichloride, determined from the following chemical equation: AlCl 2 C 2 H 5 + 3H 2 O ⁇ Al (OH) 3 + C 2 H 6 + 2HCl
- the invention it is possible to remove traces of water. less than a value given in the load, before entering the reactors, while taking a safety margin, and thus maintain catalyst activity at its best.
- the invention also has the advantage of allowing the elimination of polluting products, such as hydrogen sulfide, mercaptans and alcohols, by reaction with the chemical compound injected in accordance with the following general chemical equations: AlCl 2 R + 3 HY ⁇ AlY 3 + RH + 2HCl AlR 3 + 3 HY ⁇ AlY 3 + 3RH in which Y represents one of the following radicals: -OH, -OR, -Cl, -SH, -SR.
- the invention is not limited to the injection of ethyl dichloride aluminum to dry an oil cut to be isomerized, but, according to other embodiments within the reach of the skilled person the invention, it allows to dry many other types of cuts petroleum and, in particular, the charges of alkylation units of the type solid.
